In the first place this issue is touched on briefly in the last paragraph of the conclusion. But as I explained to the editor, I have specifically avoided discussion of the epistemological implications of this theory, as I suspect that would open up a "can of worms" that would offer an opportunity for the reviewers to argue those issues, and give them more excuse to reject the paper. Since the paper was rejected anyway, I guess the point is moot at this juncture.

I should say however that the issue of why perception operates as it does, is indeed an issue of great interest to me, and I have written a paper devoted to that subject, which can be found at:

Gestalt Isomorphism and the Primacy of the Subjective Conscious Experience: A Gestalt Bubble Model

I am confident that the reviewer would find even more to object to in that paper than he found in the present one, which is exactly why I avoided discussing it here.
